Краткое описание
Crystals of (C/sub 5/Me/sub 5/)/sub 2/Yb(C/sub 5/H/sub 5/N)/sub 2/ crystallize in the monoclinic system, P2/sub 1//c, with a = 16.092 (6) A, b = 9.883 (4) A, c = 17.872 (7) A, and ..beta.. = 98.46 (3)/sup 0/ at 21/sup 0/C. For Z = 4 the calculated density is 1.42 g cm/sup -3/. Two pentamethylcyclopentadienyl rings and the nitrogen atoms of the two pyridine molecules coordinate to the Yb atom in a distorted tetrahedral arrangement with approximate C/sub 2/ symmetry. The Yb-N distances average 2.56 A, the Yb-C distances average 2.74 A, and the Yb-Cp(centers) average 2.46 A. The C/sub 5/Me/sub 5/ rings are in a staggered configuration with respect to each other. The methyl groups of the C/sub 5/Me/sub 5/ rings are bent 0.13 to 0.31 A out of the planes of the C/sub 5/ rings away from the Yb atom. The 3278 data with F/sup 2/ > 3 sigma(F/sup 2/) refined by full-matrix least squares to an R factor of 0.031. 2 figures, 1 table.
